How a Heart Unbreaks的詞曲作者和演唱者不詳，以下是歌曲的部分歌詞：
Verse 1:
Trying to forget but it's not that easy
All the memories they won't let me be
They haunt me in my sleep
But I'm trying to be brave
Chorus:
How a heart unbreaks
When it falls in love again
But this time I know
It's not gonna break me
No, it's not gonna break me
Verse 2:
I thought I had forgotten
But I wake up feeling empty
Trying to find my way
But it's like I'm lost again
But I'm trying to be strong
And I'm trying not to cry
Chorus:
How a heart unbreaks
When it falls in love again
But this time I know
It's not gonna break me
No, it's not gonna break me
Bridge:
I won't let you break me
I won't let you hurt me again
I won't let you walk away
I won't let you make me feel this way
Chorus:
How a heart unbreaks
It doesn't take much love
To mend what was broken
And I will learn how to love again
Outro:
I won't let you break me.
